Durk D. Banks, 20, of Melrose Park was taken into custody around 3 a.m. in the 7200 block of South Green Street by police officers answering a call about someone with a gun. Police confiscated a handgun without incident, and Banks was charged with unlawful use of a weapon by a felon.

Banks was sent to prison in 2011 after police caught him with a gun with its serial numbers defaced. He was arrested in the 6400 block of South Eggleston Avenue -- also in the Englewood neighborhood -- and pleaded guilty. He was released on July 27 last year and was scheduled to complete his parole at the end of July, according to state records.

Banks performs under the name Lil Durk. He is a friend and associate of South Side rapper Chief Keef, who has also been under public scrutiny since the September 2012 shooting death of aspiring rapper Joseph Coleman, 18, not far from his boyhood home in Englewood.

The slaying of Coleman – known as Lil Jojo – garnered national attention following reports that Chicago police were looking into whether a war of words in the hip-hop community between him and Chief Keef’s crew played a role in the slaying. Hours after Coleman’s death, Chief Keef sent a taunting tweet mocking Lil Jojo.

Law enforcement sources said Lil Durk is part of the same crew that had been at odds with Coleman, a feud that investigators have documented from YouTube videos and Twitter feeds.

The sources have also said the slaying maybe tied to a conflict between the Brick Squad faction of the Gangster Disciples and the Lamron faction of the Black Disciples.

No one has been charged in Coleman's slaying.

In March, Chief Keef -- whose real name is Keith Cozart -- completed a 60-day stay in a juvenile prison for violating his probation on a gun conviction. Since then, he’s been arrested twice.

On May 20, he was arrested in the Atlanta area when police found him smoking marijuana in a hotel room. A week later, he was arrested on suspicion of speeding at 110 mph on the Edens Expressway in Chicago’s northern suburbs, police said.

Banks is expected to appear in Cook County Criminal Court for a bond hearing on Thursday, police said.

A burst of thunderstorm activity across the Chicago area in Sunday afternoon resulted in multiple injuries and a death at an event in west suburban Wood Dale, the collapse of a dome in northwest suburban Rosemont and the temporary evacuation of the music festival Lollapalooza in Grant Park downtown.
